Hello all of you hope you are in a good health
I converted my one of the project from vivado 2015.4 to 2017.4 . After changes i successfully synthesize my code but in implementation it give me this type of error(cal_val_inferred_i_1/O[3] to a signal or tied to VCC or GND ) . After analysis i found out that this error is due to less usage of my bits as One of my wire have 20 bits but i only utilized its lower 9 bits . I declare one dummy register and assign this wire on that register but problem is still not resolved
Any kind of help in this regard is appreciable .
Best,
ATIF JAVED
